Résumé
Electroforming on additively manufactured templates has the potential to become a manufacturing process for making complex metal parts in a flexible and economical way. However, the main challenge of electroforming is the high surface roughness when deposition thickness increases (thickness > 100 μm), due to the high current density on edges and co-deposition of impurities while electroforming. In this work, a hybrid electrochemical manufacturing process to fabricate high-precision metal parts is proposed combining electroplating and surface levelling to achieve thick deposits (up to 1 mm) with a low surface roughness. The presented work includes a comparative study of electroforming technologies to fabricate precision metal parts on additively manufactured templates. The potential of this methodology was demonstrated by forming a copper layer on additively manufactured ABS (acrylonitrile butadiene styrene) models. The proposed hybrid electroforming method results in a simple process design, as no specific chemistry (e.g. lack of additives) is needed. Another benefit of this indirect additive manufacturing process is the reduction of the carbon footprint compared to direct printing by usage of metal salts instead of refined metals.
